To all wh/om it may concern:

Bde itl known that I, ARTHUR Jv. HARDER, a citizen of the United States, residing at Williamsport,in the county of Lycoming and State of Pennsylvania, have invented certain new y and useful Improvements in Filters, of which the following is a specification, reference being had therein to the'accompanying drawr My invention relates to a combined watercoolerandfilter,andespeciallyto theimproved construction of the filtering apparatus, in whchthe ,points ofnovelty reside as well in the increased eiiiciency and thoroughness, VA with which the apparatus'elimiuates the impurities from the water to be filtered as in the and the ease and convenience with which the various componentparts thereof may-be removed and replaced for the purposes of cleaning and renewing the filtering material.

Figure 1 is a sectional view through. the

' filter. e Fig. 2 is a detail view.

In Fig. 1 the chamber adapted lto receive the Water tobe lfiltered is shown at A, and the' receptacle for the filtered water, which may also answer .the purpose of a cooler and is supf plied with a cock or faucet through which to' .de

draw the water, is s hown at B. The chamber A, with the iltering'apparatus, as hereinafter described, is removably connected. with chamber B by means of a flange arrangement' or'diaphra'gm at 'w and may be conveniently lifted off and put on again as often as may be desired. When the filter is in place, the diaphragm a, separates the chambers A and B. Around 'a circular opening in Athe center of diaphragm, solidly attached to the upper surface of the diaphragm and at a distance of' about one-half inch from v-the circumference of the opening, extends a circle of thin upright metalor vertical yiiange b, and concentric withiange b, at about one inch outside of it, extends a screw-threaded ange c, which is fastenedto the upper surface ofn the diaphi-agria by 4legs or `supports, leaving contracted open spaces beneath the ange c for @the passage of the water, there being a spacel d, between the flanges b' and c to be'filledwith .proper filtering material. Imperviousl'ycovl, v"efring the opening in ythe, center of the dia-4 phragm and the` flanges and c isa-.removable imperforate cap e, having a handl'ef, (which cap is separately shown in Fig. v6, where it is shown to have a auge g, which is screw-threaded for the purpose of engaging the lscrew-threads on flange 0,) and this cap may be conveniently removed at any time for the purpose of cleaning the apparatus beneath and olf-cleaning or renewing the filtering material in space d. Concentric with the opening inthe diaphragm and Asolidly at,- tached to the lower surface of the diaphragm extends downwardly a screwfthreaded flange h, to which, by means of screw-threadsat the top thereof to engage the screw-threads in the liange h, is removably connected a cylindrical-shaped filtering-chamber C. Within removably rests a perforated disk z', with a handle lo, (which disk is separately shown in Fig.,2.,) Chamber() is also provided with a pervious bottom c', made of some suitable material, and is to be filled with bone-charcoal or other suitable iiltering material. It may be conveniently removed and disk i lifted out for the purpose of cleaning and'of renewing the filtering material. From the bottom of chambei' C extends downwardly acircularvscre'wthreaded iange Z, to which, by means of screwthreads atthe top thereof, to engage the screwthreads in the flan ge Z, is removably connected filtering-chamber D, which is `of cylindrical form, slightly smaller than chamber C,0pen at the top; and having a perforated bottom, and is to be filled with suitable filtering material.A It may be conveniently-removed for the purpose of cleaning and of renewing the filtering material. The combination of parts thus described compels tlie water to be filtered, which iscontainedl in chamber A, to pass beneath liange c, through tlie spaces there,which areso 1 contracted as to prevent the passage of large impurities and act as the rst obstruction, thence through the filtering material in space d, thence over the top of ange b, thence down through the openingbeneath the diaphragm a, thence through the disk t', thence through' -the filtering material in chamber C, thence..

roo.

through thepervous bottom of this chamber,

thence through the filtering material in cham-1 ber D, and thence through the perforated bottom ofchamber 'D into'V the final receptacle or cooler known as chamber B. I believe that` this combination of parts and some of the subcombinations thereof are new, resulting in an efficiency and thoroughness in eliminating the impurities from the water to be .filtered and in a convenience in removing the component parts for the purpose of cleaning and of renewing the filtering material that are found in no other filter.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is

l. In combination, a chamber A for the water to be filtered, a diaphragm a therein, a circular opening centrally of said diaphragm, two vertical circular flanges 1) and c concentric with said opening, filtering-space (Z be tween said flanges, a removable imperforate cap e fitting impervionsly over flange c by means of screw-threads, contracted spaces for thepassage of the water beneath flange c, removable filtering-chamber C depending from said diaphragm, beneath the opening therein, and connected thereto by means of a screwthreaded flange h,a removable perforated disk i resting upon a ledge in the month of said chamber, removable filtering-chamber D depending from chamber C and connected thereto bya screw-threaded fiange I, oervions bottom in chamber C and perforated bottoni in chamber I), and chamber B to act as a receptafvle and cooler for the filtered water, all so coacting as to produce the unitary result, substantially as described.

2. In combination with a chamber A to receive the water to be filtered, a diaphragm a therein, a circular opening centrally of said diaphragm, a circular screw-threaded flange 7L extending downwardly from said diaphragm concentric with said opening, a removable filtering-chamber C depending and supported from flange h by means of screw-threads, a

screw threaded flange Z extending do 'n- Wardly from the bottom of filtering-chamber C, a second filtering-chamber D depending and supported from flange Z by means of screw-threads,both chambers having pervious or perforated bottoms for the passage of the water, substantially as described.

3. In combination with the chamber A, the diaphragm therein having a central opening, circular flange depending downward from the diaphragm concentric to the opening, a filtering-chamber removably supported from said concentric flange, a second chamber depending from and removably connected to the first chamber, and perforated bottoms for both said chambers, substantially as described.

4. In a water-filter, a chamber for the water to be filtered, a diaphragm therein having an opening'in the center, a concentric flange having a plurality of openings at the base thereof, an iinperforate cover removably secured.to said flange, and an inner imperforate flange of less height than the outer flange, substantially as described. v

5. In combination, a water-chamber A, a diaphragm c, an opening centrally thereof, filtering-chambers depending from and removably connected with said diaphragm, a removable perforated disk covering the opening in the diaphragm, a filtering-space arranged concentric of the perforated disk with a water-passage to said space and a removable cover for said filtering-space, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

ARTHUR J. IIARDER.
